Loo. STOP AND LOADER.

SPECIFICATION forming part of Letters Patent No. 431,746, dated July 8, 1890. Application filed March 5, 1890- Serial No. 342,720. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. HILL, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new new and useful Log Stop and Loader, of which the following is a specification.

This invention has for its object the below described and claimed combined log loader and stop.

The leading feature in this invention consists in an adjustable continuation of an incline portion of the'log-skidway in connection with certain stops for holding the logs.

In the drawings forming a part of this specification, Figure 1 is an elevation. Fig. 2 is a sectional elevation on line 14 in Fig. 1, looking from a point at the left; and Fig. 3

shows lettered details from Fig. 1, hereinafter described.

Referring to the lettered parts of the drawings, H is a casting secured in a vertical position to a suitable frame-work of the mill below the log-skidway .I.

At F is a power-shaft to which an oscillating movement is imparted by means of the connecting-bar f, which bar is pivotally connected at the lower end with the upper end of the piston-rod e of the engine E, and pivotally connected at the upper end with a crank D of said power-shaft F.

Referring to Fig.1,E is an engine of an ordinary construction, and N is a lever by which the operator operates the valve-rod O in letting on and shutting off the steam.

For an explicit understanding of the lever N and valve-rod O and the peculiar means herein illustrated connecting said parts, reference should be had to Letters Patent granted to me October 29, 1889, No. 413,721; but so far as the present invention is concerned any suitable lever arrangement may be employed in connection with the valverod 0. W crank-arm i of the power-shaft F is pivotaily connected the lower end of a casting A. The upper end of said casting has a straight horizontal surface I, which is thrown up against the under side of the log to be loaded into the carriage O. This casting A is thrown up by means of the engine E, and from the fact that said casting is attached to the casting H by means of the strap 0, one end of said strap being pivoted to the casting II and the other end to the casting A, as in Fig. 3. When said castingA moves upward, it also tilts forward, and thereby throws the upper part I on an incline, as in Fig. 3 and in dotted position in Fig. l. IVhen in this position, the log rolls down said incline I onto the log-carriage O. The log-skidway J is not inclined entirely to the lo -carriage, for the reason that in certain casesas, for instance, when sawing timber-the log would project far enough over the side of the logcarriage to conflict with said skidway. The upper right-hand corner of said incline I is provided with a friction-roller n, which serves as a stop to hold in check the logs back of the one rolled onto the carriage O, as illustrated in dotted position in Fig. 1.

At 13 is an arm pivoted at one end to the casting H at WV, Fig. 2. The other end of this arm 13 is provided with a roller e, and serves as a stop to hold the logs in check when not loading them on the carriage O, as in Fig. 1. This stop is operated by a bar a, which bar is pivotally connected at the lower end to a crank-arm m of the power-shaft F, and the upper end of this bar' is pivoted to the arm B at a point between its two ends, as in Fig. 1. The arrangement of the stop e B in its relation to the loader A is such'that when the loader moves up the stop moves down, thus releasing the log to be loaded. Fig. 3 illustrates this position of parts. on the other hand, when the loader A moves down the stop e B is thrown up.

Referring to Fig. 1, the piston e is provided with what may be termed two stopplates 0 and 2, one above and one below the rubber cushion d. This rubber cushion is attached to a bracket h, which bracket projects from a post of the mill. The piston e passes vertically through said rubber cushion and plays loosely therein. The object of this construction is to assist the steam-cushion in the enginecylinder in limiting the end-thrust of the piston-rod and in cushioning the shock.

For convenience of location of parts the crank power-shaft F is employed; but the loader A might be attached directly to the piston-rod and the loader may be employed independently of the peculiar log-stops herein shown, if desired.

While only one loader and the stops are here shown, a series of them of any number may be employed to act upon different parts of the logs at the same time, according to the length of said logs.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a log-loading apparatus, the verticallyplaying andlatcrally-tiltingloader having the upper straight surface, one corner thereof constituting a log-stop provided with a frictionroller, in combination with a log-stop adapted to be thrown up when the loader moves down, substantially as set forth.
